DANIEL O. DWYER, OF VIOl-IITA, KANSAS, ASSIGNOR OF TVVO-THIRDS TO RICHARD O. STEWART, JR., AND WALLACE A. STEXVART, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 482,998, dated September 20, 1892.

Application filed May 31, 1892.

T0 at whom it may concern.-

Be it known that I, DANIEL C. DWYER, a citizen of the U nitedStates of America, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification, reference being had therein to the accompanying drawings and the letters of reference thereon, forming apart of this specification, in which Figure 1 is a perspective View of the shoe; Fig. 2, a detailed perspective of one heel portion thereof having the rubber covering of the heel-spring removed; Fig. 3, a detailed sectional view of one heel portion having the rubber covering of the spring likewise removed; Fig. 4, a similar view representing said rubber covering on the spring; Fig. 5, a bottom plan view of said rubber spring-covering, and Fig. 6 a longitudinal section of the same.

This invention relates to certain improvements in horseshoes; and it consists in the particular construction of heel-springs made as a part of the shoe by Welding them to the shoe-body, and of rubber coverings made to fit over the heel-springs to be in contact with the heel of a horses foot when in service and constructed to be held in position on the springs when in service by the nails which secure the shoe to the foot, which improvements are fully set forth and explained in the following specification, and pointed out in the claims.

Referring to the drawings, S represents the shoe proper, and S S the heel portions thereof, which portions are formed with a rounded upper surface, as shown at R.

D represents the heel-springs, preferably made of spring-steel, which are attached to the shoe by being welded to the body portions thereof, one at each side, arranged extending rearward over the shoe-heel portions S, and are formed with rounded under surfaces, as shown at R ,facing the similar faces or surfaces of the heel portions S, and are made so that their upper surfaces will be on a plane with the remaining portion of the shoe, so that in fitting a shoe to a foot the hoof may be pared evenly as in the usual manner.

In the formation of the springs D they are Serial No. 435,130. (No model.)

made thickest at their junction with the shoe and taper gradually to their terminal, which gives them equality of strength through their length and adapts them better to service.

O represents a covering of rubber or some equivalent material, made in form of pockets to fit closelyover the springs D, as shown, and take the general outlines of the springs, and are provided with a forwardly-extending fiat portion 0', which rests upon the shoebody forward of the springs, and are provided with holes B, made to register with the rear nail-holes of the shoe, through which the securing-nails pass and are arranged when attaching the shoe to a foot, which nails hold the rubber and prevent it slipping off the springs. It is not essential that said holes 13 shall be made prior to nailing the shoe to a foot, for the reason that the securing-nails will readily pierce the rubber when being placed, and thereby form said holes. The purpose of the heel-springs is when in service to provide a yielding bearing for the heel of the foot wearing the shoe, to give ease to travel, and to preventtoo severe pounding of the shoulder of a horse, which occurs on hard roads with the ordinary solid and rigid shoe, and the purpose of the rubber covering 0 and its portion 0' is to provide a pad between the shoe and the heel portion of the hoof for horses having tender feet, and especially for horses having bruised feet and the like, and the form of such pads adapts them to be firmly secured in position and of a size adapted for their purpose and not cumbersome, and the purpose of the facing rounded surfaces of the heel portions S and springs D is to avoid flat surfaces between said springs and heel portions and to prevent the accumulation of dirt, gravel, or the like to interfere with the proper elasticity of the springs.

It is the intention in this invention that the heel-springs be made to yield but slightly, which avoids the liability of the shoe-nails being loosened when in service, which would be the result should the springs yield too freely.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is as follows:

1. A horseshoe provided with the heel portions thereof rounded on their uppersurface, with heel-springs welded to the shoe;body forward of said rounded portions and arranged extending rearwardly over said heel portions, being made on a plane on their upper surface with the shoe-body and rounded on their surface facing said heel portions, in combination with the rubber coverings or pads made to fit upon said springs and provided with a portion extending forwardly therefrom, adapted to be secured in position on a foot by means of the shoe-securing nails, substantially as and for the purpose set forth.

set forth.
